radiator recore (1/14)

Had a catastrophic failure on my big block with oil and radiator fluid intermixed. Had to get flushed and was told I need th radiator re-cored due to leaks that showed up after the flush. What would be a fair price for such an endeavor?

Thanks!

I have not personally had to do this, but costs seem to vary widely.  So I would say shop around, get prices and compare recore price to replacement (if that is a viable option for your Vette).

I have no experience with a recore, but here's what I would do if I was in that situation. I would buy a new Dewitt's radiator. You just don't mess around with cooling.

Best to check around at reputable radiator shops for a price as was mentioned there can be a range.

If a replacement is in order look for one with a copper core.  While aluminum ones may be lighter my mechanic contends that one with a copper core does a better job of heat transfer.

From the DeWitt's website.

Copper has better thermal conductive properties than aluminum and that is why many people ask this question. The fact is, older copper radiators are made up of (4) four different materials, not just copper. The copper tubes are bonded to the fin with solder (lead) and that has very poor conductive properties. The tanks are made of brass and the side channels are steel. An aluminum radiator is 100% aluminum and the tubes are much wider and closer together (shorter fin height) than the older copper units. As a result, you have more tube-to-fin contact and that is what removes heat.

It's been a long time since 1969. The radiator has served you well. "Be Cool" ,  "Dewitts" , Corvette America can make you one. The new one will give you peace of mind when 195 shows on the gauge. It very well may cost you a significant amount of money opposed to new to recore.

That's pretty close to a brand new DeWitts all alumimun black painted big block radiator, and it cools 30% better.

It's painted black. You can't tell the difference.

Norsky has the best advice: Whatever you do, shop around the REPUTABLE REPAIR SHOPS. I lost 900 bucks on a simple recore of my original '73's to an underhanded place. Hate to even bring it up. 

Honest shops only.

OK then!

The option for a DeWitt was never presented. Had it recored for $600. Would have gone with a DeWitt, but this one works great.

Thanks for all the advice!

In northern Wisconsin try and find a shop that will do a recore, they are far and few between. Have a shop in Rice Lake that I got a quote for $1000.00 to do the recore. This was 3 or 4 years ago and the DeWitt radiator was on sale for under $400.00 shipped to me, this was not the black one. I went with the DeWitt and I'm happy that I did, it keeps the engine nice and cool at all the time.  The only problem that I had was that I had trouble putting on the oem cap on and also the Murray replacement cap. The locking ears on the radiator neck were too long. I got a billet radiator cap from DeWitt and it fit fine. It was a little expensive, but a well built and finished cap.
